A South Korean navy ship fired warning shots at a North Korean fishing boat intruding into southern waters across the disputed Yellow Sea border, military officials said.
The vessel sailed a nautical mile into the southern side of the sea boundary at 5:26 pm (local time), prompting a South Korean patrol ship to take action, the South's defence ministry said.
“Our side fired warning shots as the North Korean vessel ignored repeated warnings to retreat,'' a ministry spokesman told AFP. “The vessel is now slowly sailing back into northern waters,'' he said.
